Pin-tailed Sandgrouse (Pterocles Alchata) White Background
The pin-tailed sandgrouse (''Pterocles alchata'') is a medium large bird in the sandgrouse family. It has a small, pigeon like head and neck and a sturdy, compact body. It has long pointed wings, which are white underneath, a long tail and a fast direct flight. Flocks fly to watering holes at dawn. The call is a loud ''kattar-kattar''. This gregarious species breeds on dry open treeless plains and similar habitats. Its nest is a ground scrape into which two or three cream-coloured eggs with cryptic markings are laid. Both sexes incubate the eggs. The pin-tailed sandgrouse is about long. Its head and upperparts are yellowish-green. The underparts are white with a chestnut breast band separating the belly from the green neck. Sexes are somewhat similar, but the female is better camouflaged and has a shorter tail than the male. There are two subspecies; ''P. a. alchata'' breeds in southern Europe and ''P. a. caudacutus'' breeds in northwestern Africa, the Middle East and southeaster ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polygonum
''Polygonum'' is a genus of about 130 species of flowering plant in the buckwheat and knotweed family Polygonaceae. Common names include knotweed and knotgrass (though the common names may refer more broadly to plants from Polygonaceae). In the Middle English glossary of herbs ''Alphita'' ( 1400–1425), it was known as ars-smerte. There have been various opinions about how broadly the genus should be defined. For example, buckwheat (''Fagopyrum esculentum'') has sometimes been included in the genus as ''Polygonum fagopyrum''. Former genera such as ''Polygonella'' have been subsumed into ''Polygonum''; other genera have been split off. The genus primarily grows in northern temperate regions. The species are very diverse, ranging from prostrate herbaceous annual plants to erect herbaceous perennial plants. ''Polygonum'' species are occasionally eaten by humans, and are used as food plants by the larvae of some Lepidoptera species – see list. Most species are considered weeds i ...

Birds Of Central Asia
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Bird ...

Pterocles
''Pterocles '' is a genus of near passerine birds in the sandgrouse family. It includes all the species in the family except for two central Asian species in '' Syrrhaptes'' These sandgrouse have small, pigeon-like heads and necks, but sturdy compact bodies. They have long pointed wings and sometimes tails. Their legs are feathered down to the toes, but unlike species of the genus ''Syrrhaptes'' the toes are not feathered. ''Pterocles'' species have a fast direct flight, and flocks fly to watering holes at dawn and dusk. Two to three eggs are laid directly on the ground. They are buff or greenish with cryptic markings. All species are resident. Taxonomy The genus ''Pterocles'' was introduced in 1815 by the Dutch zoologist Coenraad Jacob Temminck. The type species was subsequently designated by the English zoologist George Robert Gray as the pin-tailed sandgrouse. The genus name combines the Ancient Greek Ancient Greek includes the forms of the Greek language used in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Precocial
In biology, altricial species are those in which the young are underdeveloped at the time of birth, but with the aid of their parents mature after birth. Precocial species are those in which the young are relatively mature and mobile from the moment of birth or hatching. Precocial species are normally nidifugous, meaning that they leave the nest shortly after birth or hatching. These categories form a continuum, without distinct gaps between them. Altriciality Etymology The word is derived from the Latin root ''alere'', meaning "to nurse, to rear, or to nourish" and indicates the need for young to be fed and taken care of for a long duration. By contrast, species whose young are immediately or quickly mobile are called ''precocial''. Precociality Etymology The word "precocial" is derived from the same root as ''precocious'', implying early maturity in both cases. Superprecociality Extremely precocial species are called "superprecocial". Examples are the megapode birds, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ganga Cata MHNT
The Ganges ( ) (in India: Ganga ( ); in Bangladesh: Padma ( )). "The Ganges Basin, known in India as the Ganga and in Bangladesh as the Padma, is an international river to which India, Bangladesh, Nepal and China are the riparian states." is a trans-boundary river of Asia which flows through India and Bangladesh. The river rises in the western Himalayas in the Indian States and union territories of India, state of Uttarakhand. It flows south and east through the Gangetic Plain, Gangetic plain of North India, receiving the right-bank tributary, the Yamuna, which also rises in the western Indian Himalayas, and several left-bank tributaries from Nepal that account for the bulk of its flow. In West Bengal state, India, a feeder canal taking off from its right bank diverts 50% of its flow southwards, artificially connecting it to the Hooghly river. The Ganges continues into Bangladesh, its name changing to the Padma River, Padma. It is then joined by the Jamuna River (Bangladesh), ...

Asphodelus
''Asphodelus'' is a genus of mainly perennial flowering plants in the asphodel family Asphodelaceae that was first described by Carl Linnaeus in 1753. The genus was formerly included in the lily family (Liliaceae). The genus is native to temperate Europe, the Mediterranean, Africa, the Middle East, and the Indian Subcontinent, and some species have been introduced to, and are now naturalized in, other places such as New Zealand, Australia, Mexico and southwestern United States. Many asphodels are popular garden plants, which grow in well-drained soils with abundant natural light. Character The plants are hardy herbaceous perennials with narrow tufted radical leaves and an elongated stem bearing a handsome spike of white or yellow flowers. ''Asphodelus albus'' and '' A. fistulosus'' have white flowers and grow from high; '' A. ramosus'' is a larger plant, the large white flowers of which have a reddish-brown line in the middle of each segment.

Alhagi
''Alhagi'' is a genus of Old World plants in the family Fabaceae. They are commonly called camelthorns or manna trees. There are three to five species. ''Alhagi'' species have proportionally the deepest root system of any plants - a 1 m high shrub may have a main root more than 15 m long; due to their deep root system ''Alhagi'' species are drought-avoiding plants that utilize ground water, adapting in that way perfectly to the hyper-arid environment. ''Alhagi'' species are used as food plants by the larvae of some Lepidoptera species including '' Coleophora argyrella'' which feeds exclusively on ''A. maurorum''. The genus name comes from the Arabic word for ''pilgrim''. Uses in Traditional Medicine ''Alhagi'' in Persian is "KhareShotor" which means ''thistle of camels'', as camels can eat it with its thorns. As such, it was figured out that the plant can sustain the abdominal organs in severe thirst. In the Middle East, its boiled or distilled juice is used against kidney ...
